The DH77X is a compact wafer check valve installed between pipe flanges. Its spring-assisted closing mechanism provides automatic reverse-flow protection without the length of a conventional flanged valve body.
The listed model combines a cast iron body and disc with a stainless steel spring and NBR seal. It is a practical option for water and utility lines where installation space is limited.

Compact Wafer Installation
The wafer body fits between mating flanges, reducing the space needed along the pipeline. The spring assists closure as forward flow falls, helping the closing element return toward its seat.
The NBR sealing arrangement makes medium and temperature compatibility an important part of selection. For replacement work, the valve dimensions and mating flange arrangement should be compared with the existing installation.
